Study groupRoleWhat they receive
Voice ProsthesisExperimentalSubjects receive a Voice prosthesis using the Provox Puncture Set, then undergo an articulation training program (3 weeks). The voice prosthesis is replaced after 3 months and 6 months.
Receives: Device: Provox Vega Voice prosthesis

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in pronunciation effect (subjective auditory assessment)

    Voice recordings judged by two independent evaluators, scored from 1-7, with lower scores meaning worse speech.

    Measured: Baseline, 3 months, 6 months

Secondary outcomes (7)
  1. Change in longest articulation time (continuous /a/, count)

    The longest duration time of one continuous / a / is recorded by a stopwatch, count and the average of three times are taken at the same time.

    Measured: Baseline, 3 months, 6 months

  2. Change in sound intensity (minimum / maximum / comfortable);

    Sound intensity of the minimum / maximum / comfortable loudness (measured 3 times per person) is recorded to calculate the dynamic range (in decibels)

    Measured: Baseline, 3 months, 6 months

  3. Change in total time required to read a text

    Standard Chinese text is read out loud, and the total time is recorded.

    Measured: Baseline, 3 months, 6 months

  4. Change in Voice Handicap Index

    Validated tool to assess Voice handicap. Statements on participant's voice quality and effect on social life are assessed by a five-point Likert-scale, ranged from 0-4, with high scores indicating more handicap (0 = Never, 4 = Always).

    Measured: Baseline, 3 months, 6 months

  5. Change in Quality of Life by SF-36

    Patient reported, 36-item, Score of calculated, ranging from 0-100, the lower the score the more disability. The higher the score the less disability

    Measured: Baseline, 3 months, 6 months

  6. Evaluation of operative performance

    Study-specific questionnaire on feasibility and satisfaction of clinicians

    Measured: Baseline, 3 months, 6 months

  7. Incidence of Adverse Events

    Any adverse events (including serious adverse events and device defect rates) will be recorded.

    Measured: Baseline, 3 months, 6 months

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in pronunciation effect (subjective auditory assessment) (time frame: Baseline, 3 months, 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
